Specification of Letters Patent.

Patented May 15, 1906.

Application filed April 27, 1903. Serial No. 154.379.

To all whom, it may concern:

Be it known that I, EDGAR A. GAY, of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Furniture-I-Iinges; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the reference characters marked thereon.

My present invention has for its object to provide an improved form of hinge adapted particularly for connecting portions of ad justable furniture and which will automatically lock the movable part or parts thereof in any desired position and also to enable their relative angular adjustment to be altered at the will of the operator.

To these and other ends the invention consists in certain improvements and combinations of parts, all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the specification.

In the drawings, Figure 1 is a side elevation of a hinge constructed in accordance with my invention. Fig. 2 is a similar view showing the parts at the limit of their opening movement. Fig. 2 is a sectional view on the line 2 2 of Fig. 2. Fig. 3 is a view similar to Fig. 2, showing the locking-bar in the inoperative position. Fig. 3 is a sectional view on the line 3 3 of Fig. 3. 4 shows the position of the parts when the hinge members are being returned to their normal position. Fig. 5 is a view illustrating the operation of releasing the locking-bar. Fig. 5 is a sectional view on the line 5 5 of Fi 5.

imilar reference characters in the several figures indicate similar parts.

A hinge constructed in accordance with my invention embodies two members A and B, pivoted together by a stud or rivet 1 and adapted to be attached, respectively, to the stationary and movable parts or pieces of furniture or other objects. In order to hold the hinge members in adjusted position, I provide upon one of them a toothed bar, adapted to engage with a projection or abutment upon the other member and also suitable devices for supporting the bar in the inoperative position to permit the hinge members to be closed when desired. The member A is provided with a wing or projection 2, provided with an elongated slot or aperture 3 therein, having the lower end forming an abutment with which cooperate ratchetteeth 4, provided upon a bar 5, pivotally attached to the member B. These ratchetteeth are inclined in one direction, so that as the hinge members are separated they will successively engage with the abutment to hold the parts in adjusted position, as illustrated in Figs. 1 and 2. At its outer end the bar 5 is provided with a point 6, adapted when the last tooth on the bar is in engagement with the abutment to act as a cam against the face of the flange 2 to force the end of the bar upwardly to disengage it from the abutment if the hinge members are separated a greater distance, as shown in Fig. 3. Also arranged on the wing 2 is a laterallymovable supporting member constructed of a plate 7, pivoted upon a rivet or stud 8. At its lower end the plate is provided with an outwardly-projecting end 9, having at its inner edge a lip or projection 10, normally bearing against the side of the bar, as shown in. Fig. 2. The pivotal point of the member is preferably arranged above the bar 5, permitting it to operate by gravity into the position shown .in Fig. 3 when the bar has been moved out of engagement with the abutment, as before explained.

In order to make the swinging movement or operation of the supporting member positive, I have provided thereon a projection 15, located at one side of the pivot, adapted to be engaged by the upper edge of the bar 5 and operated by the latter into the position shown in Fig. 3 as the bar moves away from the abutment. The disengagement of the supporting member is automatically effected by the bar when the hinge members are returned to the normal or closed position, and to this end the edge of the lip 10 is cut away at an angle, as shown at 16, providing a beveled surface which cooperates with a projection or enlarged tooth 17 on the bar 5, arranged in such position that as the hinge members approach the limit of their closing movement, as shown in Fig. 5, the swinging member will be moved outwardly, allowing the bar to drop into its normal position in readiness for a subsequent operation.

A hinge constructed in accordance with my invention requires but few parts all capable of beingformed of sheet metal and which may be easily assembled.

By providing the laterally-extending wing on one of the hinge members the supporting member maybe conveniently mounted there on, and by projecting theend of the lockingbar through an aperture formed in the wing the bar is always held in juxtaposition to the abutment and there is no possibility of the parts becoming displaced during shipment or by careless handling.

I claim as my invention 1. A hinge consisting of a member having an abutment, a second member hinged to the first having a bar thereon provided with teeth adapted to cooperate with the abutment and a supporting member on the first mentioned hinge member movable transversely of the path of the bar to hold it out of engagement with the abutment.

2. A hinge consisting of a member having an abutment, a second member pivoted to the first having a bar provided with teeth and a swinging supporting member movable laterally of the bar to hold it out of contact with the abutment.

3. A hinge consisting of a member having an abutment, a second member pivoted to the first having a bar provided with ratchetteeth adapted to engage the abutment and a cam operating to raise the bar out of engagement with the abutment, and a pivoted supporting member movable laterally into engagement with the bar.

4.. A hinge consisting of a member having an abutment, a second member pivoted to the first having a bar provided with teeth adapted to engage the abutment, means for raising the bar and a support separate from the bar for holding it out of engagement with the abutment, and means for moving the support to the inoperative position to release the 5. A hinge consisting of a member having an abutment, a second member pivoted to the first having a bar provided with teeth adapted to engage the abutment, and with means cooperating with the abutment to raise the bar and a support separate from the bar for holding it out of engagement with the abutment and cooperating surfaces on the support and bar for disengaging the former from the latter.

6. A hinge consisting of a member having an abutment, a second member pivoted to the first having a bar provided with teeth adapted to engage the abutment and means for raising the bar, a swinging supporting member pivoted to the first-mentioned hinge member and operating beneath the bar when the latter is raised and means for disengaging said supporting member from the bar when the hinge members are closed.

7. A hinge consisting of a member having an abutment, a second member pivoted to the first having a toothed bar engaging the abutment and means for disengaging the bar therefrom, a pivoted laterally-movable supporting member operating to hold the bar out of engagement with the abutment and means on the bar for disengaging the said member therefrom.

8. In a hinge, the combination with a member having a wing projecting therefrpm and provided with an aperture and a second member pivoted to the first, of a bar journaled on the second member having its end projecting through the aperture and provided with teeth adapted to engage the edge thereof and a cam on the bar cooperating with the abutment for raising the bar, a supporting member pivoted above the bar and adapted to engage beneath the latter when it is elevated and means for automatically op erating the supporting member to release the bar.

9. In a hinge, the combination with two pivoted members, a flange on one forming an abutment, a bar pivoted to the other member and provided with teeth adapted to cooperate with the abutment and means for disengaging .the bar therefrom, of a member pivoted to the flange having a lip and a pro jection extending in the path of the bar and adapted to be engaged thereby to move the lip out of operative position.
